It will be necessary to refrain from getting too excited, especially since the source of today’s rumor is the controversial Moore’s Law Is Dead, but according to its sources, AMD is considering turning Grimlock Ridge into a real fireworks display to celebrate the end of life of the AM5 platform.
In November 2025, MLID had already presented what the two types of “consumer” CCD should be for the future Zen 7 architecture: Silverton and Silverking. Tom does not revisit this point, but here are the characteristics he advances for these two versions in a small table:
| CCD | Surface | Cœurs | L2 | L3 | Option 3D V-Cache? | |————–|———–|——-|——-|——-|———————| | Silverton | 98 mm² | 16 | 32 Mo | 64 Mo | Oui: 160 Mo | | Silverking | 56 mm² | 8 | 16 Mo | 32 Mo | Non |
With a maximum configuration of two Silverton CCDs, each equipped with 3D V-Cache, similar to what we currently know with the arrival of the Ryzen 9 9950X3D in Zen 5 architecture, one could hope for a Grimlock Ridge flagship composed of 32 Zen 7 cores and 320 MB of 3D V-Cache (448 MB of L3 Cache in total).
That wasn’t too bad, but Tom has just released a new video explaining that AMD is considering bringing something even more powerful to AM5 and consumers, with the CCD Steamboat, normally reserved for EPYC! Hang on tight, because here is what he thinks a Steamboat CCD would look like using the TSMC A14 lithography:
| CCD | Surface | Cœurs | L2 | L3 | |———–|———–|——-|——-|—————-| | Steamboat | 117 mm² | 36 | 72 Mo | 252 Mo (stack) |
Although “3D V-Cache” is not directly mentioned here, the idea is similar. According to MLID, the main die surface with cores and L2 Cache would be 107 mm², and directly below it would be another “stacked” die of 117 mm² containing all 252 MB of L3 Cache of the CCD. Impressive quantities of both cores and L3, especially considering it is only one CCD. As you can see, the rumor becomes quite wild here: MLID is selling dreams by saying that if AMD follows through with this idea and offers an ultimate version of its latest AM5 generation processors with two of these Steamboat CCDs, we could have a CPU with 72 Zen 7 cores and 504 MB of L3!
Well, let’s calm down, because even MLID is cautious about the possibility of Steamboat coming to AM5 for consumers. Nevertheless, a little dreaming doesn’t hurt sometimes, right?
